Chazelle, 1436 Virginia Drive, Ellisville, M0. 63011 Filed Nov. 9, 1967, Ser. No. 681,848 Int. Cl. E04g 21/16 U.S. Cl. 294-35 3 Claims bottom wall thereof, latching means interposing both said hand-hold and said `wall for releasably securing said former with said latter, as when said former is disposed in eithenaxial or transverse Vrelation with saidlatter selectively, support means for holding said carrier.in an elevated position in respect to the plane of a restingrsurface, in a manner whereby said hand-hold may be freely grasped by the user thereof, actuating means interposing said support means and said handhold yfor simultaneously moving the former inwardly said apron as when said latter is disposed in its said axial position thereby, said carrier will further serve .as a building material hawk, free of projecting appurtenances.

"My invention relates to a portable carrier for storing therein, `a fluid or plastic building material, formuse by building decorators or wall paperers, as well as by others, and more particularly to a material carrier that may be used in a manner simulating that of a building material hawk.

The invention residing in a material carrier having means adapted to support the carrier in an elevated plane superposing that of a planar resting surface, with said means being cooperative with a second means that serves to balance the carrier as when sustained within one hand of the user, whereby the carrier will be relieved of projecting appurtenances therfeabout.

Heretofore, the practice of sustaining a carrier holding a selective fluid or plastic building material, generally required the journeyman, as well as by others to sustain the carrier for use, by clutching one end or side wall within his hand, with the thumb thereof overhanging the wall thereof inwardly the carrier that generally constituted a condition whereby the thumb became contaminated with the material, `and if this practice was consistent, the thumb soon became painful to the user by the irritation thereof, and furpher I have found it burdensome'forthe user to sustain a4 carrier from one end or side thereof in -anfhorizontal plane whereby a` material stored thereinfwould be retained in a substantially level position, as ordinarily the material would have a tendency to either spill or creep from the confine ofthe carrier, and consequently either contaminate his clothes or the floor of the building and possibly both.

It therefore being the main object of my invention to provide a building material carrier having means whereby the carrier may be balanced centrally the under side thereof, as when sustained for use within the grasp of a users selective hand. l

It being another object of my invention to provide a portable carrier for fluid or plastic building materials having means whereby the carrier may be. rested on a planar surface in an up-right position wherebyit may be servicedwith a selective material.

A further object of my invention is to provide a maa 3,476,431 a Patented Nov. 4, 1969 ice terial carrier having means interposing the first and second stated means whereby the second stated means may be made cooperative with the iirst stated means whereby the carrier will be relieved of projecting appurtenances as when used in a manner simulating that of a material hawk.

A still further object of my invention is to provide a material carrier of the aforementioned characteristics that may be transported in a manner simulating that of a carrying case. Y

Additional attributes of my invention reside in its simplicity of design and construction, durability, economy of manufacture and the assembly thereof, with other advantages becoming apparent after the description hereinafter set forth is consideredin conjunction with the related` drawings annexed hereto.

In the drawings wherein like or corresponding parts or elements are identied by identical numerals, wherein:

FIGURE 1 is a perspective yiew in side elevation of my improved portable carrier for plastic or uid building materials having certain outer portions removed therefrom in order to reveal other inner elements of construction.

FIGURE 2 is a view in longitudinal section taken substantially on the line 4-4 of FIGURE 1.

FIGURE 3 is an identical view substantially as that shown in FIGURE 1, however, to best illustrate the invention from the stand-point of unity, for this reason the upper body structure has been illustrated in an phantom view.

Referring now in detail to FIGURE 1 wherein the portable carrier for fluid and plastic building materials is identified by the numeral 10, and is shown to comprise in combination a pair of upstanding, paralleled spaced side walls 11, 11, a pair of end walls 12, 12, each of which being spaced inwardly the opposed vertical edges of the side walls, whereby both the side and end walls mate integrally with the sector shaped corner members 21, 21, 21, and 21 respectively, and disposed inwardly the lower marginal edges thereof there is provided an integral bottom wall 13, and depending from the lower marginal edges thereof there is provided an apron 14 therebout, and for reasons hereinafter apparent the material carrier 10 is formed of a ferrous metal that may be rust proofed following the assemblythereof.

-Nowreferring to FIGURES '2 andf 3 there is shown a channel bracket 26 that depends'from the central portion of the bottom wall 13, that "is weldingly secured to the under-side 15 thereof by the accommodating ears 2li- 28, in a manner whereby the channel passage therethrough transverses the central portions'of the end walls defined by the apron 14.

The channel bracket 26 serves as a housing for a pinion 21 disposed centrally therein having the radial teeth thereof spaced inwardly the upstanding iianges of the bracket 26, and which pinion 21 'interposes in contiguous relation both the web member 25 thereof and the `bottom wall 13 whereby serving to limit the axial movement of a pintle 27a that depends iixedly and centrally from the pinion 21 thatis accommodated to pass centrally through the web member 25, and rotatably a flat* spacer bearing 24 that depends iixedly from the yweb member and depending ixedly and centrally from the extensible end portion of thepintle 27a, therewith is provided a bight member '20, 20, having the limbs 19, 19, thereof, spaced equally from the central and longitudinal axis of the pintle 27a, and which limbs serve to secure therebetween as at their intermediate end portions a hand hold 18 of circular cross section, that is adapted to receive threadedly through the central transverse end portions thereof the threaded screw fasteners 3 23, 23, that are accommodated to pass through the limbs 19, 19.

The hand hold 18 is adapted to project axially and medially from the plane of the lower marginal edge of the apron `14 whereby serving to stabilize the carrier 1t) when resting upon the users open wrist of the respective hand that is positioned about the hand hold 18, as when supporting the carrier for use, in a manner simulating that of a material hawk, it now being readily apparent that the weight of a plastic or fluid material as may be selectively stored within the carrier may now be readily balanced centrally thereof, and thereby increase the physical endurance of the user; and when the carrier is to be serviced with a selective material, as when resting upon a planar surface in an upright position, there is for this purpose provided a leg structure as henceforth described.

Disposed in opposed meshing relation with the pinion 21 and extending through the open sides of the channel bracket 26 in parallel vopposite directions there is provided a pair of racks 36, 36, that include integral shank members 35, 35, that are guided slidably by the channeled brackets 40, 40, as when the opposed lateral ears 41, 41, of each respective bracket 40 are weldingly secured to the under-side 15 of the bottom wall 13, whereby obviating the lateral movement of the racks 36, 36, from the pinion 21 which would obviously disengage the mating teeth thereof.

Formed with the intermediate end portions as at 37a of the shank members 35, 35, there is provided in depending and lateral relation with each thereof, a bearing link 37 that extend equally from the opposite open sides of the channeled `bracket 26, and when in a fully extended position they are each adapted to journal slidably therein, within the lower semi-circular end portion thereof a transversely disposed crank-pin 34 that extends radially and in depending relation with a respective integral crank-shaft 33 that is rotatably supported as at 38a by the pair of spaced bearings 38, 38, that are secured weldingly to the underside 15 of the bottom wall member 13 as by the opposed lateral ears 39, 39, provided with each thereof, in a manner whereby each pair of bearings 38, 38, will be spaced inwardly and equally from an adjacent end wall 12 of the carrier 10` whereby they will each permit a substantially U-shaped leg frame 16 to `be outwardly inclined from the lower marginal edge of an adjacent end wall of the apron 14, as when each leg frame 16 is weldingly secured at the terminals of the limbs thereof to the terminals provided at the free ends of a pair of quarter bends as provided with the terminal portions of each respective crankshaft 33, in a manner whereby the leg 4frames 16, 16, will be `both adapted to lbe extended equally from the central and vertical axis of the carrier 10 when serving to support the carrier 10 in an elevated position, as when the -bight member 17 of each leg frame 16 is resting upon a planar surface that is superposed by the hand hold 18 whereby the user may grasp the under-side thereof when raising the carrier in an upright position `by the use of a selective hand.

It now being apparent from the foregoing description wherein it has been pointed out that when the leg frames 16, 16, are `in a fully extended position that the crankpins 34, 34 are disposed in the lower semi-circular end portions of the bearing links 37, 37, and which positioning corresponds to the transverse positioning of the hand hold 18 in respect to the carrier 10, it therefore being obvious, and as it is illustrated in both FIGURES l and 3, that `by manually rotating the hand hold 18 in a clockwise direction in respect to the fixed position of the carrier 10 will in turn provide a pulling action simultaneously on the crankpins 34, 34 through the medium of the linear movement of the racks 36, 36, and the bearing links 37, 37 respectively, whereby the cranks 34, 34, will be influenced to move slidably and upwardly toward the upper semi-circular portion of the bearing links 37, 37, respectively, and it follows that the leg frames 16, 16, will be moved accordingly into a substantially horizontal plane as is illustrated in FIGURE 2, wherein the leg frames 16, 16, are adapted to be interposed by the axial position of the hand hold 18 in respect to the carrier 10, and conversely the leg frames 16, 16, may be selectively extended into diverged relation, as when the first stated rotatable action on the hand hold 18 is reversed in respect to the fixed positioning of the carrier 10.

To preclude the possibility of the leg frames 16, 16, converging into a collapsed state, as when supporting the carrier 10 in an elevated position, though being well stabilized as by the respective bight members 17, 17 thereof, as may possibly occur when a material within the carrier 10 is being agitated by the user during a mixing process, and conversely to obviate the reverse movement of the leg frames 16, 16, as when in a retracked position, as may accidentally occur by the shifting of a material within the carrier 10 which would in turn have a tendency to turn the carrier about the iixed positioning of the hand hold 18 as when sustained in the hand of the user, there is therefore provided for the forementioned reasons a pair of latching members 29,129, each of which serves alternately to be releasably secured with the hand hold 18 in one of the two previously described positions thereof in respect to the carrier 10.

The latching members 29, 29, are each formed of a iiat spring steel ribbon having an upwardly inclined arcuately shaped portion formed with one extremity thereof that constitutes an indexing finger 32, and adjacent thereto there is provided a depending semi-circular portion that constitutes a catch member 31, and provided with the opposite extremity of the latching member 29, there is provided a short return bend that constitutes a tongue member 30 that is spaced from the latching member 29, in superposed and parallel relation therewith, each tonguev member 30 serves to support each respective latching member 29 to the under-side of the bottom wall 15 in a plane complementary to that of the bight member 20 associated with the hand hold 18 as when weldingly secured therewith, and in a manner whereby one of the pair of catch members 31, 31, is disposed centrally and transversely the central and longitudinal axis of the bottom wall 15 with the other respective catch member 31 being disposed centrally and transversely the central and transverse axis thereof, and further wherein each catch member 31, 31, is spaced radially from the pintle 27a thereby each indexing iinger 32, 32 will intercept medially a respective side portion of one outer end portion of the bight member 2i) of the hand hold 18 as when the bight member 20 is oscillated alternately therebetween by the medium of the hand hold 18, whereby the abutting relation between the bight member and a respective indexing iinger member 32 will influence the finger member to rise slidably thereon, and further influence the catch member 31 to follow accordingly, thereby the catch member will enter into latching relation with a complementary slot 22 formed centrally the bight member 20 therethrough, and conversely the catch member 31 will be forced from .the slot 22 as when an initial thrust is applied manually on the hand hold 18 in a direction complementary for either extending or retracting the leg frames 16, 16 selectively whereby the initial thrust will influence the catch member 31 by the medium of the curved body portion thereof to rise resiliently therefrom, as when abutted by a respective inner side portion of the periphery surrounding.

the slot 22.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts.
